  - The DrawDashPolygon function in 'MagickCore/draw.c.' script mishandles
    calculations of certain vertices integer data.

  - The TraceStrokePolygon function in 'MagickCore/draw.c' script mishandles
    the relationship between the BezierQuantum value and certain strokes data.

  - The DrawImage function in 'MagickCore/draw.c' script makes an incorrect
    function call in attempting to locate the next token.");
